General Burkhalter sets up a trap whereby a security leak is traced to Stalag 13. This gives Burkhalter enough ammunition to replace Klink with a tougher and more efficient camp commandant. It is up to Hogan to discredit the replacement and ferret out the "mole" within his own ranks. Familiar Hanna-Barbera voice-over actor John Stephenson, a frequent Hogan's Heroes guest star, is here cast as Major Kohler. Written by Laurence Marks, "Information Please" first aired on December 23, 1966. ~ Hal Erickson, Rovi
